CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 256,587, dated April18, 1882.

Application filed November 14,1881. (No model.)

To alt whom it may concern:

Beit known that I, STEPHEN S. NEWTON, a citizen of the United States ofAmerica, residing at Binghamtomin the county of Broome and State of NewYork, have invented certain new and useful Improvements in Chandeliers;and I do hereby. declare the following to bear full, clear, and exactdescription ofthe invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to letters or figures of refereucemarked thereon, which form a part of this specification.

This invention relates to improvements in chandeliers for holding lamps,&c., in such manner that they may be vertically adjusted in position,the invention pertaining more especially to that classofchandeliersillustrated in a patent granted to me March 14, 1 876, No.174,841.

The object of the present invention is to so construct the chandelierthat it can be made more ornamental than could those that have beenheretofore used, and also arrange the parts so that the shell whichsupports the lampbrackets and conceals the adjusting and lockingmechanism shall be smaller than it could be made when the parts werearranged in the manner heretofore common.

Figure is a vertical section of a chande- 'lier embodying some of myimprovements. Fig. 2 is a vertical section of a somewhat modibrackets 0.Any suitable number of the latter may be employed, and each carries atthe outer end a socket or recess, D, for the reception of the lamp. 7

. Within the shell or easing E thereis mounted a shaft, F, by means ofany suitable journals or boxes. This shaft F carries a drum or cylinder,G, and also one or more cogged wheels; or,instead of cogged wheels, thedrum G may beflanged and the flanges cogged or toothed, as shown at b b.

To the drum G is attached acord, flat band, or chain, H, which not onlyconnects and holds together the two parts of the chandelier, but also,in combination with the drum or cylinder G, enables the lifting up ofthe outer and lower part of the chandelier by the winding of the cord,band, or chain upon the drum or-cylinder.

- The supporting device may be made in the form of a chain, as shown, orof a narrow piece of flexible sheet metal. When made in the form of achain the separate links may have central apertures to engage withsprocketteeth, or the links may be without such apertures.

In order to hold the shell E (and with it the lamps) at any desiredpoints, I combine with the parts described the following devices:

I I are dogs connected to the inner side of the shell-or casing bypivots, the dogs being of suitable length to engage at their inner endswiththe cogged flanges or wheels at b b. By examining the drawings itwill be seen .that these dogs I I are situated and swing in planessubstantially at right angles to the axis of the drum.

J J represent arms pivoted at their upper ends to the dogs I, as shownat 6. These arms are preferably-joined rigidly together at their lowerends, or formed from one piece of metal, and are connected rigidly to adownwardly-extending rod, K, which passes through the bottom of thecasing or shell E, and is made of any suitable length. The greater partof that portion of this rod K which is not concealed within the shell orcasing E is covered by a supplemental shell, which in the drawings isflanges I). However, to insure a downward movement of the rod K and thepart L a spring, k, may be combined with the rod, arranged to bearagainst the shell and the rod, substantially as shown.

M is a coiled spring placed around the shaft F, and arranged to wind upa cord or hand, H, when the dogs I are released from thetoothed wheelsor flanges I).

At i there is a ring or hook joined by a swiveling connection to theinner tube, B, so that the whole apparatus can rotate about it, the ringor hook being attached to any suitable support on the ceiling. The innertube, B, and the outer tube, A, can be prevented from rotatingrelatively to each other by means of one or more grooves or slots in oneof the tubes, as shown in Fig. 3, and in the other tube one or more pinsor lugs adapted to engage with said grooves or slots.

It will now be seen that it the hand of the operator be pushed upwardslightly against the ball L the rod K will be moved upward and the dogsI will be released from the toothed wheels or flanges at b, and that thespring at M can then operate to draw up the shell E, and with it thelamps.

When the movable parts are at the desired point they can be secured bywithdrawing the hand from the ball L, for this permits the rod K to dropdown and brings the dogs into engagement with the teeth at I).

A n importantadvantage which I have gained by arranging the slidingtubes relatively to each other as shown--tbat is to say, arranging theupper or stationary tube inside of the slidingtubeisthatthelowerpartcanbemadc much more ornamental than is the case when thelower or sliding tube is arranged inside of the upper or stationary one.Thus objects of oruamcntation-such as globes or shells or leaf-work ofany suitable character, as at 0- may be attached to the lower or slidingpart,

or may be formed integral therewith. When this arrangement is followedthe parts of the chandelier which are brought down into the lower parts.of the room can be made much more ornamental than when the inner tube isarranged to slide.

In addition to the improvements above set forth, others may be embodiedin a chandelier, which are'shown in the drawings, and which I will nowdescribe, referring more particularly to Fig. 2.

In the construction shown in said figure, at the upper end of the innertube, B, a small supplemental shell or casing, P, is employed to receivethe supporting ring or hook at i, and also to hold the springshaft Q,and the winding-drum. The said shaft may be mounted in the manneralready described. In the lower shell or casing, E, there is mountedanother shaft, ,F, to which is attached a drum, B, there being toothedor cogged wheels or flanges b, as already described for the otherconstruction. The drum R in this case is provided with sprocket teeth orin gs 7c 7r, whereby it is adapted to engage with a chain, S, and in theconstruction shown in Fig. 2 is provided also with a spring mechanism atM. One end of the chain S is secured tothe fixed parts of thechandelier-as, for instance, at the upper end of the inner tube, or thelower end, or at any suitable point. The other end of the chain issecured to the winding-drum G.

The parts I, J, K, L, f, and g may be the same as those shown in Fig.l-that is to say, so arranged that the drum It may be prevented fromrotating by allowing the parts K and L to hold the dogs I in engagementwith the toothed wheels or flanges b. When it is desired to bring thelower parts of the chandelier downward the parts K and L are thrustupward to release the dogs, and the casing E is then pulled down, thisoperation resulting in a winding up of the springs on shafts Q and F.When the lamps have been brought down far enough the rod K is releasedand the dogs are again brough t in to enga gem en t, after which thelamps will be locked in position. When the lamps are to be carriedupward the dogs are released in the manner described, and the springs MM rotate the drums G and It and wind up the chain S, which lifts orpulls up ward the casing E and the lamps. When the latter are at thedesired point they are again locked, as before.

In Fig. 5 I have shown a modification of the mechanism which controlsthe rotation of the chain spool or drum, which consists in theeurployment of flexible stops instead of the hawls and detcnts, and in thefigurcTT are flexible or elastic strips or hands, preferably of thinmetal. Each strip is attached by one end to the shell or other desiredpart of the lower rising and falling portion of the chandelier, andpassing over and resting upon the upper portion of the periphery of afriction-wheel, U, which is rigidly attached to the drum or spool shaft,thence down to a cross-head or T-piece on the upper end of rod K, sothat the weight of the rod and bar L is suspended upon the bands orstrips, which are thus made to serve as frietion-stops, and when desiredthe pressure of these stops upon the friction-wheels U maybe furtherincreased by means of the spiral spring h. Thus it will be seen thatthese parts oper' ate as a friction-stop to hold the wheels U, theshaft, and the chain-drum in any desired position. I

By examining Fig. 2 it will be seen that, whether the additional orsupplemental spring be used on shaft F or not, pawls I and ratchetteethI) can be made to regulate the rotation of drum R, and thus permit thespring within the shell P to wind up the chain. It will also be seenthat by using the supplemental spring on shaft F additional power may beapplied to lift the chandelier. This construction also permits the useof very flexible springs by reason of their duplication, therebyproviding for the requisite amount of rise and fall with less danger ofbreaking the springs than would be involved in the use of aslnallernuinber of stiffer springs. I

In the patent previously granted to me, dated March 14, 1876, I showed achandelier having the telescoping tubes, a bulb at the lower end, alocking mechanism in said bulb, and a stop operated by a rod through thebottom of the bulb.

In the construction herein shown I have done away with the eccentricdevices shown in the said patent for locking the winding mechanism, andarrange the operating-rod to extend directly to the locking devices,avoiding the use of the supplemental pivoted parts shown in that patent.Moreover, in the presentconstrnction I so arrange the operating-rodaudits dog or pawl that under ordinary circumstances the weight of theseparts shall operate to hold the pawl in engagement with the ratchetsthatis to say, the dogs or pawls are situated above the winding mechanism,so that the rodby its gravity will tend to pull them downward; A spring,however, is shown, as it may be used to assist the gravity of the rod.Again, in the aforesaid patent the locking-dog was situated in a planesubstantial] y parallel to the axis of the ratchet-wheel, and itvibrated in the plane of said axis. When so placed there necessarilyresults much torsional strain upon the dog, and especially upon itspivoting support. In the present device the dogs vibrate in the planesof the rotation of the ratchet-wheels, and they therefore en gage withthe wheels to much greater advantage than when the other arrangement isemployed. All twisting and straining are removed from the operatingparts and a much heavier spring can be employed. What I claim is 1. In achandelier, the combination, substantially as hereinbefore set forth, ofthe following elements, namely: the telescoping supportingtubes, anexpanded bulb carried by the lowertube, a chain or flexible supportingdevice counccting the tubes, a coiled spring, and adrum concealedentirely within said bulb, the drum adapted to engage with the chain andto be rotated by the spring, and mounted on a shaft situated across thecentral line of the telescoping tubes, a stop-wheel which is rotated bysaid shaft, a locking-piece which atoneend is fastened in the plane ofrotation of said stop-wheel and at the other is movable in said planeinto and out of engagement with said wheel, and an operating-rod passingthrough the bottom of the inclosing-bulb.

2. In a chandelier, the combination of a stationary tube, a slidingtube, a bulb carried by the sliding tube at or near the lower endthereof, a drum mounted at or near the upper end of the stationary tube,a spring which rotates said drum, a drum situated and concealed entirelywithin said bulb, a chain extending from the upper drum downward aroundthe lower drum, and thence upward to the stationary tube, a stopmechanism which engages with the lower drum and prevents the winding ofthe chain, and an operating rod extending downward from said stopmechanism,substantially as set forth.

3. In a chandelier, a winding drum and spring attached to the upperstationary tube, adrum and spring attached to thelower sliding tube, achain attached to the upper drum, pass ing downward around the lowerdrum and up to and attached to the stationary tube, and a stop mechanismto limit the rotation of one of the drum s, both of said drums'bein gconstructed and arranged to engage with the chain, substantially as setforth.

4. In a chandelier, the combination, with the toothed flanges band thevibrating dogs I, of the arms J and the rod K, substantially as setforth. Y Y

In testimony whereof I affix my signature in presence of two witnesses.
